The format of the abstract is as per this document. The length of the abstract should not be longer than one A4 size page in any case. The font for the abstract is $12pt$ Times New Roman font.

If you have any figures, you should make them as pdf documents and upload the pdf figures along with the tex file. \par
You can put figures and references in your abstract. In general, we do not recommend more than one figure in your abstract. Figures can be included using the commands given below. In place of Yourfigure, type the name of the file that contains the figure you would like to put here. Your directory should consist of a file called Yourfigure.pdf. \par
We do not recommend equations in the abstract but they can be included if they are necessary. You can test your file for errors by compiling this file using the command \\
pdflatex yourfile.tex \\
This will help you appropriately modify your file. Finally you will submit the LaTEX file (yourfile.tex) with the figures zipped into a single file on the Registration website.
